Excellent disc! If I could, I would like to request some additional patterns for consideration please:
a) please add a 75% white to the Color Patterns for both Rec 709 and 601 (so we have r,g,b,y,c,m and now White too). My software package prompts me to measure white in addition to the primaries and secondaries, and without this I do not have a 75% white anywhere else on the disc to use (and it needs to match the 75% of the other colors).
b) please consider making the color patterns also available at 100%
c) please add a set of IRE windows that go by 5 IREs (5, 10, 15 etc). Or if not then please add a single 5 IRE window. I can measure accurately at 5 IRE and like to dial that in.
d) please consider adding a pattern that consists of 6 horizontal bars from 0 to 10 IRE (0, 2, 4, 6, 8, 10) as this helps give a good idea of how things hold up in the low end.
